Fix a bug which made Go!Cam, GPS and sceKernelLoadExecVSH not work in game mode.

PSN downloaded PSX games support wasn’t working in 3.51 M33 (didn’t work in latest OE’s either). Now it is working again. If an original PSN game still doesn’t work, we recommend to delete the KEYS.BIN file if it exists, and copy the game again from PS3 to PSP.
